SPECIFICATION forming part of Letters Patent No. 702,019, dated June 10,1902. Application iiledlvannary v64, Serial ENQ. 90,043. (Nomodel.)

ciently fluid from a main to a measuring-receptacle may be automatically arrested or cut oi when a predetermined quantity shall have passed into such4 measurer, :such,auto-.

matic cutting off of the supply of liquor to the measuring-tank When the desired qu anti ty shall have entered same being eected by the rising therein of a float and the reverse action.

of a counterbalance-weight attached to a cord or chain and intermediate connections revolving a striking pin or pointer into engagement with av trigger and connections controlling in; let and outlet valves reversely. The descend- Iingaction of the iloat as the fluid is drawn off reverses the revolving direction of a second pointer, revolving it into engagement with a reversely-set bell-trigger, thus automatically signaling the instant the iiuid Vin measurer shall have been drawn olf.

Referring to the drawings, which form a part of this specification, Figure 1 is an elevaton of the whole apparatus including the quantitative scale and automatically-.operating mechanism; Fig. 2, a side view of annular quantitative scale, striking scale-pointer, signal-striking pointer, and cone-shaped or tapering revolving barrel with oord or chain passed around same and adjustable Aguidefork for keeping such cord or chain in true position on barrel when latter is in motion.

Fig. 3 is a view of adetail.

A is the main or supply tank; B, the measuring-tank, which may respectively be made of any size or shape, accordingto requirements, and of any suitable material.

In the measuring-tank-B is a 'fioat C, connected to chain or cord D, working in pulleys E E', such cord or chainbeing passed around the revolvingbarrel I,"the end of such cord carrying or suspending a counterbalanceweight F, such barrel I being suitably mount- I ed horizontallyon spindle I2 in rear of fixed annular quantitative .scale G, such barrel I carrying a striking pin or pointer H around 'such scale in its annular course, as hereinlafter described. f The counterbalance-weight F is controlled in its downward course by the ascentofl the float C on the surface of the iiuid as it flows in and gradually rises in the measurer B, such iioat being the heavier, so that as the iloatrisesin B the barrel I is -set in annular motion by the balance-weighty F as vit descends proportionately to the ascent inB of such iioat C. By releasing the setscrew Hf the pointer H is freed to be moved by hand to point to any number on the annular scale representing the desired Aquantity of liquor to be drawn off into the measurer B--as, for instance, five and a half I gallons-as the pointer appears set in the drawings, Fig, l. isvthen clampedgsecur'ely to an annular pro- When so set, the pointer jectin'g rim I on inner end of the barrel I by means of set-screw H. The counterbalance-- Yweight F descending, the barrel I is caused to revolve, carrying the pointer H around in itsv course till such pointer H meets, engages with, and bears down the projecting triggerarm U, (overcomin g the supporting-spring V,) releasing the trigger T,attac hed to the end ofrcordv or chain S, when the balance-weight O ot the'b'ell-crank lever L M, mounted pivotally on standard K, falls, operating such bell-crank lever L M, thev arm M of which carries a signal-bell m in the cord or chain N, attached to such arm L, suspending plug P of inlet-valve Py of measurer B. The end of cord or chain Q is attached to bell-crank lever X, (mounted pivotally on standard'YJ suspending by cord or chain Z'the plug P2 of outlet-valve P3 of measurer B, the cord Q 'beingpassed through eye in said arm M, the

IOO

let-valve l?3 of the measurer B the instant the predetermined quantity of fluid shall have passed from A into B, leaving the fluid in B free to be drawn off by the tap B2 when desired. As the liquor is being drawn off from the measurer B the float C descends, causing the counterbalance-weight F` to ascend in unison with C, thus reversing the annular motion of the barrel I, (see Fig. 2,) and the pointer h (attachable to the rim of such barrel similarly to H) when such descending float reaches the bottom of recess W in measnrer B, engages with trigger a, and releases the bell-trigger arm b from the trigger a, causing the bell c, attached by steel strap to b, to ring, intimating that the measurerB is emptied ready to be reset, as before de scribed. It will thus be readily understoodsayin a bntter-factory-in the sale and measuring 0E to customers of skim-milk the attendant may set the apparatus to measure off a given number of gallons by the trigger mechanism described and leave the apparatus to complete the operation automatically and the purchaser to draw olf by tap B2 the measured amount of his purchase, the first and final steps in the operation being signaled to such attendant automatically as they conclude, as before described.

Referring to portion of Fig. 1 and Fig. 2, an eyehole in the butt-ends of the pointers H h, respectively, receives loosely the fore end of set-spindle I2, on which they are placed. An under plate is provided on each pointer to correspond with the fore enlargement of such pointers, such under plate and enlargement lying apart, so as when compressed by setscrew to form a clamp H2, in which the annular projecting rim I on fore end of barrel I passes, so that so long as the pressure of setscrew H' is released the clamp H2 remains open, leaving the pointers H h free to be turned in either direction to right or left around the annular scale G to any desired number on such scale representing the number of gallons required to be measured off when by means of such set-screw H the clamp H2 is closed and securely tightened on such annular rim I', when such pointers become fixtures to the barrel I, such barrel and pointers thenceforth (till released) moving as one piece. In Fig. 2 the annular quantitative scale G is mounted on four legs G', projecting horizontally from frame mounting the barrel I. The feet of such legs are set in segmental slots on rear frame and secured by bolt and nut G3, so as to be capable of being moved around to right or left for convenience of adjustment of the scale in its exact position when fitted in the first instance or subsequently if requiring correction or readjustment. G`1 is an adjustable or chain guide sliding on one of the legs G' and secured by set-screw G5, in which such cord or chain works, keeping it in true position on barrel I, determined by figure on scale G at which pointer H is set. The object of making such barrel I cone-shaped or tapered is that when used for, say, measuring skim-milk in a butter factory the process of separating the cream takes off with the cream more or less milk, not always a uniform quantity, entitling the dairyman to a little more or less i return over or under in the form of skim-milk, in which case the graduated or tapered shape of the barrel I permits of its being set to measure off a little more or less than the predetermined number of gallons, which would not be the case were the barrel I of uniform circumference.

It is obvious that a suitable framework for mounting and supporting the operating mechanism and connections before described would have to be provided; but to avoid confusion such framework (save in a few instances) has been omitted from the drawings, the small Fig. 3 therein denoting the various points where parts would require to be attached or mounted to such frame. It is also obvious that the pointers H h, moving integral with the barrel I, obviate any possible inaccuracy in the measuring operation by reason of climatic or atmospheric influence on the cords or chains used in and with the apparatus.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In combination, a main tank A, a measuring-tank B, an inlet-valve between the main and measuring tanks, an outlet-valve from the measnring-tank, a float C in the measuring-tank, a trip device, an adjustable pointer connected with the float for operating the trip, a bell-crank R connected to the trip, a pair of bell-crank levers L M and X connected with the bell-crank R and connections from the pair of bell-cranks to theinlet and outlet valves, substantially as described.
